We're looking to change the icon for the system tray for DWRCST. I know about disabling the icon entirely, but we'd like to re-do the icon for branding purposes.
I could probably extract and replace the icon in the exported msi files (from the Dameware Remote Control Client Agent MSI Builder) but that can be a PITA.
There is not a currently supported method of customizing the tray icon. To your point, there are a few ways to hack through the image replacement, but nothing presently supported.
